Specification forming part of Letters Patent No. 3,429, datediFebruary 12, 1844-;Eessued p September 5, 1846, No. 85.

To all 'wh-0m it may concern Be it known that I, ABRAM Pnisn, of Lyons,

, in the county of lVayne and State of New York, have invented anewand useful Improvement in `Rotary SteamfEngines; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had tothe annexed drawings, making a part of this specification, in which- Figure l (on Sheet l) is an isometrical projection of that part of the engine which embraces the parts constituting my claim; Fig. 2 (on Sheet 2) a view of the engine and l (also on Sheet 2) geometrical representations of details.

To enable others skilled in theart, to make and use my invention, I will proceed to describe its construction and operation.

@obstruction-On the beams or sleepers A rests and is fastened the oblong frame B, on the top of the end or cross pieces of which frame, and in themiddle of them, are placed he boxes C, secured by screws or bolts. i In these boxes revolve the gudgeons of the main shaft D. Near` one end of the said shaft is the revolving steam-cylinder E, furnished with its usual appendages, viz:` the stationary plate, piston, apertures for admitting and letting-off steam, two or more slides and their connecting ro-ds. The aforesaid parts being so well known, `and their construction and application so well understood, it is deemed superfluous to enter here into a minute description of the same. Near the other end of the shaft D, and at right angles with it, arebolted the arms F, two or more innumber according to the number of slides used. To the ends of these arms are attached the cranks G, by means of shoulders, `screws and` nuts; and are bent into a quarto-circular shape, gradually di-` minishing in thickness, andassuming (transversely) a square shape toward their extremities. Here they are furnished each with the transverse `head-piece H, the ends of which are semicircularly shaped. Near y these ends, at rightangles with theheadpieces andin a direction receding fromthe axis of the` main-shaft D, are fastenedby means of screws-the short shafts QI, on

` lution.

by the thickness of the curved rim hereafter" described and the diameter of the friction- Y rollers I. u i A Transversely with the main p shaft, between the longitudinal frame-pieces B, and in a vertical position, is fixed the curved rim K. `One-half of this rim (and somewhat more) stands perfectly vertical, when at o above, and at ZJ below it recedes, in the direction from the cylinder E, to a distance of about one-seventh part of its owndiameter, until it reaches the points c and cl, where it resumes again a vertical direction. `On each of its sides, nearlyin the direction of its horizontal diameter', and on its periphery, it has protuberances 7c, which rest on the frame B, whereto it is fastened by screws o-r bolts. Theabove mentioned crank-heads or transverse head-pieces II have in their centers, on the sides opposite to where the shafts and rollers I are placed, similar shafts Z, i

which tend toward the axis ofthe main shaft. To these shafts are fixed the connecting or guide-rods L, in a parallel direction with the main-shaft, which, as their namesindicate, connect with and guide the piston-rods M, by means of joints m, constructed in the usual manner.
